The daily rankings of the world’s 500 richest people listed in the Bloomberg Billionaires Index showed the top 3 remained the same on Saturday. Zuckerberg is now worth $81.6 billion, nearly $400 million more than Buffett, chairman of the Berkshire Hathaway investment group.

Zuckerberg’s California-based social network business has more than 2 billion active monthly users. The company’s stock has reached a record high despite ongoing scrutiny over its Cambridge Analytica data breach that leaked personal information of up to 87 million people, MarketWatch reported.

Zuckerberg has pledged to give away 99 percent of his Facebook stock away in his lifetime, his Bloomberg profile shows. Further, Zuckerberg has given $3.58 billion in stock sales away this year alone to a charity initiative he set up with his wife, Priscilla Chan, in 2015.
